Pyroelectricity of Pyrite and Application to Prospectingin Taibai Gold Deposit

Studies on pyroelectricity of pyrite have been made in taibai gold deposit, Shannxi Province. Pyrite occurs maily N-P-type and p-type electricity conduction (N-electronic conduction,p-hole conduction). High P-type content and high absolut value of pyroelectricity coefficient indicated the good mineralization.From upper to lower of the ore body, from west to east of the ore belt, the P-type content is going down.That shows the denudation rate of ore body from large to small. Contour map of absolute value of pyroelectricity coefficient and isothermal map calculated from pyroelectricity shows that the deep and east of KT8 is the prospective ore area.The pyroelectricity differs with the kind of wallrock that may be result of the difference of deep of ore-forming.
